It's a busy day today, but you're used to a packed schedule, right? You'll venture further into Iceland today, first visiting the Thingvellir National Park. The Thingvellir plain is in on the boundary where the Eurasian and American tectonic plates are pulling away from each other, creating dramatic rivers and fissures across the plain. Next, you'll see Geysir, known as the original hot water geyser which gave all the others their name. You'll look over a valley of eerie blue pools and mud pots, then continue to Gullfoss on the Hvita River to see a two-tiered waterfall cascading into a canyon.
At Fridheimar Greenhouse, you'll see how they grow Mediterranean vegetables in the Icelandic climate using clean geothermal energy. This is where you'll stop to eat, sampling their home-grown tomatoes. Dinner is served at Olverk Pizzeria and Brewery tonight. You'll get a tour and tasting before feasting on delicious pizza and sinking a well-earned G&T, poured over 500-year-old glacier ice. Later, you'll take a midnight dip in the Reykjadalur Hot Creek – it'll be a welcome cocoon of warmth under the midnight sun.
